COAL AND ORE CARRIER AND TRANSMITTER.

SPECIFICATION forming partof Letters Patent No. 279,264, dated June 12, 1883.

Application filed April 13, 1893. (No model.)

To all whom it may concern:

Be it known that I, FRANK Munenrnovn, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and Improved Coal and Ore Carrier and Transmitter,- and I do hereby declare that the following is a full, clear, and complete description thereof.

The special purpose of this invention is for loading coal into vessels by carrying the coal from the pile to the vessel and dumping it therein, or for unloading the vessel and transferring the coal to the pile, as the case maybe.

Although the above-specified purpose is the special object of the invention, said invention is, however, equally well adapted for unloading vessels of other freight, as ores, grain, and other commodities of a commercial nature.

The abovesaid invention can also be used fbr'transferring coal, ore, &c., from one particular placein the yard to another, or for loading the same into railway-cars and wagons for transportation.

Of the construction and operation of the invention above alluded to, the following is a full and complete description, reference being had for'illustration to the annexed drawings, making a part of this specification, in'which Figure 1 represents a side elevation of the loading apparatus Fig. 2, a detached section; Fig. 3, a plan view of the apparatus Fig. 4, a vertical transverse detached section taken through the line as m, and viewed in the direction of the arrow 1; Fig. 5, a view of a section in the opposite direction of the arrow 1; Fig. 6, a vertical transverse section taken throu h the line 90 x and viewed in the direction of the arrow 2. Fig. 7 is a transverse vertieal detached section taken through the line 00 m, and viewed in the direction of the arrow Like letters of reference refer to like parts in the several views.

As shown in the drawings A A represent a track, which may be of any desirable form and more or less in length, as circumstances may require. Said track is suspended from a suit (Not shown in the drawings, as it forms no part of this invention, and-is not essential to a proper understanding thereof.) Said frame is m ounted upon wheels or rollers, that it may be moved from place to place, as may be necessary.

B, Fig. 1, is a carrier suspendedi'rom the track above alluded to by means of the carwheels I) D and C C, Fig. 3, 011 which the said carriage is moved along thereon, as and for a purpose presently shown.

The carriage above referred to consists of a pair of sides, preferablyof metal plates, Eand F, Figs. 1 and 5, connected to each other by suitable braces and bolts, (I. Said plates depend from the outside of the track, as seen in the drawings. The upper corners of the plates are ire-enforced by means of the disks G,

through which the bolts H pass, forming the axles of the several wheels of the carrier.

Between the two plates orsides of the carrier is pivoted at b a lever, A, having three arms, I, J, and K, Fig. 1. Each of said arms terminates in a conical-shaped end, forming a hook, as shown at 0, d, and c, Fig. 1. Throughthe end 0 of the tri-armed lever A is inserted a pin, f, Fig. 3, the use of which will hereinafter be shown.

L, Fig. 1, is a lever consisting of two corresponding sides, as seen in Fig. 3, also in Figs. 5 and 6. The axis of said lever is at I), the ends of which are connected to each other, respectively, by the bars g h. The bar "h passes across the arm K of the trial-med lever A, and over the free end of the spring M, Fig. 3.

The opposite end of the spring is made'fast to said lever A at 1', as seen in the drawings.

N, Fig. 1, is a conductor or guide provided with a flaring mouth. Said guide is secured between the sides of the carrier at or near the bottom, and by which the lower edges of the plates of the carrier are connected to each other and braced thereby. The upper part of the conductor or guide is slotted, as seen in Figs. 5 and 6, to allow the depending arms of the levers A and L to play backward and forward between. the sides of the carrier.

In Fig. 1 one side or plate of the carrier is represented as broken away, that the several levers and the conductor may be seen, also the wheel 0, journaled in the corners of the carrier.

P is a sheave hung in a yoke or-bail, Q, from the lower-end of which depends a hook, R. The upper end of the yoke is abar, j, by which the yoke and sheaveare suspended from the hook dol'thelever A, as shown in Figs. 1 and 2.

To the carrier is attached one end of the rope S. Said rope passes under the sheave 1 and over the wheel O, and extends therefrom to a hoisting-machine. (Not shown in the drawings.

At each end of the rail-track above described, or at any other place or places thereon that circumstances may require, are secured, respectively, the stops T and U. The stop T consists of the clampsV V, Figs. 3 and +11, iitted to the rails of the track and the frame there of, and secured in place by the bolt 71'. In the projecting end Z of the stop are two lugs, m 11), Figs. 1 and 3, immediately above which is a pawl, 01, Fig. 1. Said stop is adjustably connected to the railway, that it maybe moved along thereon in either direction as the distance to run the carrier may require. The stop U, above alluded to, is similar to the stop T, and consists of the clamps \V \V, Figs. 3 and 7, secured to the railway by a bolt, 1), that it may be adjusted thereon, according to the distance that the carrier is required to run along on the said track or way.

the above-described appa- The operation ot ratus is as follows: Let it be supposed that the carrier 13 has been moved in the direction of the arrow shown in Fig. 1 and become attached to the stop U bymeans of the hook c, terminatingthe arm K'ot' the lever A, by said hook being caught on the stop-catch a, as indicated by the dotted lines I),- and, furthermore, that the hail of the sheave l is detached from the hook (I and the sheave lowered to the load to be raised, to which it is attached by the fallhook It; and, also, that the rope S is connected to the hoisting-maehine, which, as above said, is not shown in the drawings; now, as the machine winds up the rope, the sheave, with its load, is carried upward until the upper end ol' the bail or yoke Q enters the guide M, and is conducted thereby so far up as to impinge upon the lever L, which. at this time in the position indicated by the broken lines c, Fig. 1.. This action of the bail forces back the lower end ot" said lever L to the position shown by the full lines, which, as a consequence, depresses the upper end of the.lever down upon the spring M and the arm, K of the lever A, causing said arm'K to become disengaged from the stop-catch a, thereby advancing the hook (I of the lever A from the position indicated by the broken line (1 to that shown by the full line, which, as will be seen, is caught under the barj of the bail or yoke Q of the sheave, by which it suspends the sheave and the load attached thereby from the carrier, which is now released from the stop U, allowing it, together with the load, to be drawn along the track or way by a continuous winding up of the rope by the hoisting-engine. \Vhen the carrier reaches the stop T, the hook e of the arm I of the lever A" impinges upon the pawl n, Fig. 1, which forces down the end of the lever, so that the pin f falls on the inner side of the stopcatches on m, as indicated by the dotted lines thereby holding the carrier from moving back or away from the stop T, so that the load may now be lowered to the place in which it is to be deposited, which is done by reversing the movement of the hoisting-machine, thereby unwinding the rope for that purpose. That the load may be lowered, as above said, the bail or yoke of the sheave must become detached from the hook (I of the lever A. This, however, has been already done by thedepression oi'the arm I of the lever A, as above described. The depression of the arm I, as a consequence, forces the hook (I of the arm (I from its engagement with the bail of the sheave, as shown, back to the position indicated by the dotted lines (1, so that the'sheave and'the load suspended therefrom are free to belowered by the reverse ac; tion of the hoisting-machine, as above stated. The sheave having beenlowered, as above described, it may be again hoisted with or withouta return load. the end of thebail of which, as the sheave is drawn up by the rope, enters the guide N and impinges upon the lower end of the lever L, thereby causing the hook (Z to engage the bail, and at the same time disengaging the pins f from the stop catches or lugsm m, between whiehthe end of the anal passes, that the pins may be caught thereby for the purpose specified. The carrier, thus loaded and released from the stop T, is allowed to travel back down the track or way as th e rope unwinds from the hoisting-machine. This return movement of the'carrier is et't'ectet'l by gravity, the track being graded for that purpose. The can rier arriving at the stop U, (it may be more or less distant from the stop T,) the sheave is lowered for discharging the load as follows:

hen the carrier has reached the stop U, the

arm K' of the lever r is forced upward by the inclined plane of the stop U. (Indicated by the dotted lines C, Fig. 1, shown. in full in Fig. 3.) This upward action of the arm K causes the hook c to engage thestop catch or lug a, as in dicated by the broken lines I), which, as hereinbcfore described, disengages the hook (Z from the bail of thesheave, so that the sheave may be lowered that its load may be discharged, which being done, the operation may be again repeated,.each operation being substantially alike.

The ofiice of the'lever L and the spring Mis to keep the bail of the sheave in proper position when'h'ooked on, and to accomplish the hooking, as above stated.

WVhat I claim as my invention, and desire to secure .by Letters Patent, is
